The treatment methods for the rotten skin of the flat-tailed tortoise are as follows:

1. Thoroughly remove the lesions and apply medicine to the wound once a day. If the flat-tailed tortoise eats, add oxytetracycline to the food, and apply Sick tortoise isolation. You can take a bath every other day, but don't put it in the water and put it in the water after recovery.

2. You can choose povidone-iodine, erythromycin eye ointment, chlortetracycline eye ointment, and Baiduobang for medication. There is no need to repeat the medication, just choose one of the drugs. It is best to soak the utensils for raising turtles with potassium permanganate solution every day.
